Enterovirus 71 (EV71) is a common etiological agent of hand, foot, and mouth disease and fatal neurological diseases in children. The neuropathogenicity of severe EV71 infection has been documented, but studies comparing mouse models of severe and mild EV71 infection are lacking. The aim of the study was to investigate the neurovirulence of EV71 strains and the differences in serum cytokine and chemokine levels in mouse models of severe and mild EV71 infection. Nine EV71 isolates belonging to the C4 subgenogroup (proposed as genotype D) displayed infectivity in human neuroblastoma SK-N-SH cells; moreover, ultrastructural observation confirmed viral particle replication...

Human enterovirus 71 (EV71) and coxsackievirus A16 (CA16) are the two major causative agents of hand-foot-and-mouth disease (HFMD). To investigate novel combined vaccines to prevent EV71 and CA16 infection, we constructed chimeric virus-like particles (tHBc/SPA or tHBc/SP VLPs) displaying conserved epitopes of EV71 (aa 208-222 of VP1 and aa 248-263 of VP2) and CA16 (aa271-285 of VP1) using a truncated hepatitis B virus core carrier (tHBc). Immunization with the chimeric VLPs induced epitope- or virus-specific IgG and neutralization antibodies against EV71 and CA16 in the mice...

Enterovirus 71 (EV71) has caused major outbreaks of hand, foot and mouth disease. EV71 infections increase the production of many host cytokines and pro-inflammatory factors, including interleukin (IL)-6, IL-10 and COX-2. Some of these molecules could stimulate the signal transducer and activator of transcription 3 (STAT3), which plays a key role in regulating host immune responses and several viral diseases. However, the role of STAT3 in EV71 infection remains unknown. This study found that the phosphorylation levels of STAT3 (p(Y705)-STAT3) are closely related to EV71 infection...

Enterovirus71 (EV71) is recognized as the main causative agent of severe hand, foot and mouth disease (HFMD). However, the pathogenesis of EV71 infection has not been well characterized. Clinical evidence indicated that inducible nitric oxide synthase (iNOS) induction in the lung of HFMD patients contributes to the severe symptoms of pulmonary edema. In the present study, we recruited 142 subjects including HFMD patients and controls, and serum level of nitric oxide (NO) was determined. Next, cellular and animal model were used to further investigate the roles of iNOS and mitochondria damage during EV71 infection...

Coxsackievirus A6 (CVA6) has recently emerged as one of the predominant causative agents of hand, foot, and mouth disease (HFMD). Structure of CVA6 mature viral particle has not been solved thus far. Our previous work shows that recombinant virus-like particles (VLPs) of CVA6 represent a promising CVA6 vaccine candidate. Here, we report the first cryo-electron microscopy (cryo-EM) structure of CVA6 VLP at 3.0 Å resolution. CVA6 VLP exhibits the characteristic features of enteroviruses, but presents an open channel at the two-fold axis and an empty, collapsed VP1 pocket, which is broadly similar to the structures of enterovirus 71 (EV71) VLP and coxsackievirus A16 (CVA16) 135S expanded particle, indicating that CVA6 VLP is in an expanded conformation...

BACKGROUND: Enterovirus 71 (EV71) is one of the causative agents of hand, foot and mouth disease, which mostly affects infants and children and leads to severe neurological diseases. Vaccination offers the best option for disease control. We have screened the virus strain FY-23 K-B, which is used as an inactivated vaccine strain. An important issue in the development of vaccines is whether they provide cross protection against all other strains. METHODS: We collected and identified 19 clinical EV71 isolates from mainland China, which all belong to the C4 genotype...

Enterovirus 71 (EV71) is the major causative agent of severe hand, foot and mouth disease which affects millions of young children in the Asia-Pacific region annually. In this study, we engineered a novel EV71 virus-like particle (VLP) that lacks VP4 (thereby designated "VLPΔVP4"), and investigated its structure, antigenicity and vaccine potential. The cryo-EM structure of VLPΔVP4 was reconstructed to 3.71 Å resolution. Results from structural and biochemical analyses reveal that VLPΔVP4 resembles the end product of the viral uncoating process, the 80S empty capsid...

Toll-like receptors (TLRs) act as molecular sentinels, detecting invading viral pathogens and triggering host innate immune responses, including autophagy. However, many viruses have evolved a series of strategies to manipulate autophagy for their own benefit. Enterovirus 71 (EV71) and coxsackievirus A16 (CA16), as the primary agents causing hand, foot and mouth disease (HFMD), can induce autophagy leading to their replication. Therefore, the objective of this study was to investigate whether enhanced viral replication caused by autophagy in EV71 and CA16 infections was associated with a TLR-related signaling pathway...

In recent years, hand, foot, and mouth disease (HFMD) has been increasingly recognized as a critical challenge to disease control and prevention in China. Previous studies have found that meteorological factors such as mean temperature and relative humidity were associated with HFMD. However, little is known about whether the diurnal temperature range (DTR) has any impact on HFMD. This study aimed to quantify the impact of DTR on childhood HFMD in 18 cities in Sichuan Province. A distributed lag non-linear model was adopted to explore the temporal lagged association of daily temperature with age-, gender- and pathogen-specific HFMD...

Enterovirus 71, as one of the dominant pathogens associated with severe hand, foot, and mouth disease, has been well reported to trigger severe neurological symptoms among young children over the last decade, particularly among children in the Asia-Pacific region. To date, no effective antiviral agent has been developed for the treatment of severe enterovirus 71 infection. PNU-282987, a selective alpha 7 nicotinic acetylcholine receptor (α7nAChR) agonist, has been reported to have a neuroprotective effect by participating in inflammatory regulation in previous studies...

Enterovirus 71 (EV71) is associated with the severe hand foot and mouth disease (HFMD) outcomes, however the host-virus interaction mechanism and the pathogenesis remain poorly understood. Long non-coding RNAs (lncRNAs) are involved in variety physiological and pathological processes, but the functions of lncRNAs in EV71 infection remain elusive. Here we profiled the expression of lncRNAs in peripheral blood mononuclear cells (PBMCs) from EV71-infected mild patients, severe patients as well as the healthy controls, and identified 8541 lncRNAs were differentially expressed...
